CROSS-REFERENCE TO RELATED APPLICATIONS

This is a continuation-in-part of and claims the priority benefit under 35 U.S.C. 120 of U.S. patent application Ser. No. 13/185,686 entitled Pipe Pitch Article, System and Method of Installation, filed Jul. 19, 2011, the entire disclosure of which is hereby incorporated by reference.

FIELD OF THE INVENTION

This application relates generally to pipes employed in installations in buildings and other facilities that utilize piping systems for the transport of liquids.

BACKGROUND OF THE INVENTION

This invention provides an article, system and an installation method to insure that the proper pitch is employed in piping systems for the transport of liquids, typically constructed from plastic formulated pipes, such as a polyvinylchloride (PVC) and used in homes, offices and other facilities, generally. Although potable water and waste water, are the most frequent substance transported other fluids such as natural gas and gasoline are transported from one location to another via complex networks of pipes. These networks of pipes typically include long, relatively straight lines that enter into and exit from enclosed spaces, with occasionally intersected branches, and that may additionally bend around various enclosure walls and support structures, making it difficult to maintain a decreasing elevation as the piping progresses over its intended route. One problem with the use of piping systems is to insure that the pitch is in the direction of the sink and away from the source to insure the proper rate of flow and that liquid does not stagnate or worse, have impeded flow because pipes are pitched in the wrong direction. Presently there does not exist any device that insures a fool-proof means to install piping, especially in a rapid production fashion, that guarantees that the piping system is pitched properly, can be installed properly by a relatively unskilled work-force and is virtually no more expensive than the product without such advantages. With the foregoing in mind, the present invention will be distinguished over the prior art in the description and application of new components, design criteria and utility to the field of the invention.

SUMMARY OF THE INVENTION

This invention provides a novel apparatus in for holding a pipe in fixed association with a mounting surface. It is used for constructing a piping system including a least one stanchion, said stanchion having affixed thereto a pipe mount, vertically adjustable on the stanchion, for fixing a dimension from the pipe mount to a stanchion mounting surface. The apparatus may include two or more stanchions and associated pipe mounts that are used to insert the pipe, the distance between the pipe mounts and the mounting surface designed to create a pitch of the pipe in the direction of the sink and away from the source of a liquid to insure the proper rate of gravitational flow.

The stanchion attaches at one end directly to a support such as a floor or ceiling. Affixed to the stanchion is an adjustable pipe mount having a recess (usually in the shape of a cylindrical pipe) such that when a pipe is inserted within the curvature of the recess, the pipe is secure. The position of the pipe mount on the stanchion serves to establish a fixed distance between the pipe relative to the mounting surface, such that when the pipe is mounted in the pipe mount recess as an element of a piping system, a pitch of the piping system is provided in the direction of the sink and away from the source of a liquid to insure the proper rate of gravitational flow. In what follows, when the dimension of the stanchion is referred to, it is meant to include the added dimensions of any boss, or a mounting foot if used.

This invention also relates to a system for pipe installation including one or more pipes, each of which pipe is in fixed association with two or more stanchions, and its related pipe mount, said stanchions having a mounting foot for affixing the foot to a mounting surface, each said pipe mount adjusted to set a vertical distance from the pipe mounted thereon to the mounting surface.

The stanchion included herein is comprised of three parallel vertical beams, a center beam for guiding the pipe holder mount, and two outer beams, one on each side of the center beam, having teeth to engage a corresponding set of teeth on the pipe mount for securing the pipe holder in position and thus fixing a pipe a measured distance from the mounting surface. The mounting surface referred to is generally horizontally positioned, however in certain applications the surface may be vertically positioned, as described below.

The invention herein further refers to a method for pipe installation including, mounting one or more pipes each said pipe in fixed association with a two or more stanchions, said stanchions having a mounting foot and a pipe mount, for establishing a fixed distance between the pipe mounted in the recess relative to the mounting surface, in a piping system to provide a pitch of the one or more pipes in the direction of the sink and away from the source of a liquid to insure the proper rate of gravitational flow.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a perspective view of the pipe pitch apparatus 100 in accordance with one embodiment of the present invention. Stanchion 101 is used as the mounting device for a pipe mount 104 to hold by way of example and not limitation a common pipe for transporting liquids. The pipe mount 104 is secured to the stanchion 101 via a U-channel (See, FIG. 3), a tab 105 and the intermeshing of teeth (FIG. 2( d)). A mounting foot 109 secures the stanchion to a plane surface, such as a floor, ceiling or wall, affixing foot 109 to a mounting surface utilizing a fastener, such as a nail or screw, all by way of example. A pipe recess 103 secures a pipe once inserted into the opening. The stanchion can be ganged or extended by placing a stanchion having a dove tail into the slot 107.

FIGS. 2 a, b, c and d illustrates plan views of the apparatus 100. FIG. 2 (a) show the frontal view of the Stanchion 101 comprising three beams, 111 a, 111 b, and 111 c and having mounted thereon the pipe mount 104. A tab 105 serves to fix U-channel 125 (FIG. 3 (b)) once it is inserted into the spaces between the two outer beams and the central beam of the stanchion. The side view FIG. 2 (d) and FIG. 2 (b) and corresponding Section A view, shows teeth 113 situated on beam 111 a that intermesh with teeth 115 that are situated on the rear interior 119 section 117 of the pipe mount 104 as illustrated in FIG. 2 (d). (Note: the separation between the teeth 113 and teeth 115 in FIG. 2 (c) is only shown to clarify the two sets of teeth).

FIG. 3 (a, b) are plan views and FIG. 3 (c) is a perspective view of the pipe mount 104 that affixes to the stanchion 101. As shown in FIG. 3, a rail 123 is inserted into a rectangular channel 129 shown in FIG. 2 (c), and FIG. 4 Section A in the rear of I-beam 111 b that extends from the top of the stanchion 101 to the mounting foot 109. The rail 123 and the channel 129 provide added support to the pipe mount 104, and increase its load bearing capacity.

Returning to FIG. 3, U-channel 125 is spring loaded due to the material of the pipe mount 104, and the dimension of the U-channel relative to the beam 111 a and beam 111 c, respectively over which the U-channel fits. Once the U-channel 125 members 121, 127 slide into the beam 111 a and 111 b, respectively the tab 105 secures member 127 by gripping the front surface of 111 a and beam 111 c, respectively to retains the pipe mount 104 fixed along the horizontal cross-section of the stanchion 101.

Turning to FIG. 2 and FIG. 4 Section A, the pipe mount 104 is fixed along the vertical or length-wise dimension of the stanchion with the aid of the intermeshing of teeth 115 affixed to the pipe mount 104 and the teeth 113 affixed to the beams 111 a, and 111 c rear surfaces, respectively.

As shown in FIG. 4 and FIG. 5 related pipe 108 used in a series of piping, creates a piping system. The pipes of this invention may be represented by a through-pipe that may be inserted into a female portion of a union to achieve longer length or pipe runs. The pipes as the term is used in reference to this invention also may be represented by the union itself, i.e., the pipe-section having a female portion to accept longer pipes having smaller diameters than the receptacle into which it fits. By way of example, the pipes 108 illustrated in FIG. 4 may be designed to connect to other pipes through unions to extend the overall length of the pipe 108. Furthermore, the invention, by way of example and not limitation, includes pipes such as a through pipe-section, a nipple, an insert, a union, a bulkhead fitting, a conduit, or valve. Additionally, as by way of example pipes 108 may have sizes referred to in the plumbing industry as Schedule 40 or Schedule 80, among other sizes as may exist in other industries.
